The depths of the planet are some of the strangest and weirdest places we have available to us. We've talked about oceans before, but this week, on The What If? Podcast, we're going spelunking - and diving deep into caves. We're talking natural, manmade, deep, wide, spooky—everything and anything related to the weirdness of the tunnels that bury deep into our earth. From Greece to China to Russia, we explore the mysterious, exciting, and frightening, underground parts of our world.
